The Portland Police Bureau and the Oregon State Police are teaming up on Sunday in a crackdown on drunken drivers.

Their message: "Think Before You Drink." If you do, arrange for safe transportation to Super Bowl festivities.

According to U.S. Department of Transportation's National Highway Traffic Safety Administration, impaired drivers make Super Bowl Sunday one of the most dangerous days on the road. Nationwide, approximately 48 percent of traffic fatalities on Super Bowl Sunday involve a driver or motorcycle operator with a blood alcohol concentration of 0.08 percent or higher.

The agencies said if you're attending a Super Bowl party or watching the game at a sports bar or restaurant:

If you don't have a designated driver, ask a sober friend for a ride home; call a cab, friend, or family member to come and get you; or if possible stay where you are for the night and don't drive until you are sober.

Never let a friend drive drunk. Arrange a safe way for them to get home.

Always buckle up. It's still your best defense against other drunk drivers.

If you're hosting a Super Bowl party:

Make sure all of your guests designate their sober drivers in advance, or help arrange ride-sharing with sober drivers.

Serve plenty of food and non-alcoholic beverages at the party.

If you plan to stay sober, offer to drive guests home.

Encourage guests to pace themselves.

Host your party like they do at the stadium. Stop serving alcohol at the end of the third quarter of the game. The fourth quarter is perfect for serving coffee and dessert.

Keep the phone numbers of local cab companies on hand and take the keys away from anyone who is thinking of driving drunk.

Remember, you can be held liable and prosecuted if someone you served ends up in a drunk-driving crash.
